“…Significant intramolecular aurophilic interactions are found in the complexes, with the Au(I) ··· Au(I) distances in range of 2.99–3.35 Å. These values are comparable to those reported in other gold(I) chalcogenido complexes . The Au–S bond lengths are also typical of those found in the gold(I) μ 3 -sulfido complexes reported in the literature. − The gold(I) atoms are each coordinated to one phosphorus and one chalcogen atom, with the coordination distorted from an ideal linear geometry.…”

Decanuclear gold(I) sulfido clusters, [Au 10 {μ-Ph 2 PN(R)PPh 2 } 4 (μ 3 -S) 4 ](PF 6 ) 2 ], with propeller-shaped structures were obtained using bridging bis(diphenylphosphino)amine with alkylpyridine pendant groups (R = −CH 2 Py, −CH 2 CH 2 Py). The cluster, [Au 10 {μ-Ph 2 PN(CH 2 −o-Py)PPh 2 } 4 (μ 3 -S) 4 ](PF 6 ) 2 , was found to crystallize in three different pseudopolymorphs with emission colors varying from blue to green to red. Unprecedented mechanochromic, solvatochromic, thermochromic, and acidochromic properties were also observed with RGBY emission colors. From the X-ray crystal structures and powder X-ray diffraction (PXRD) analysis, the luminescence changes were attributed to the transition between different pseudopolymorphs upon external stimulus.

“…These values are comparable to those reported in other gold(I) chalcogenido complexes. [25] The AuÀ S bond lengths are also typical of those found in the gold(I) μ 3 -sulfido complexes reported in the literature. [49][50] The PÀ NÀ P angles of the ligands are approximately 120°while the dihedral angles between the phenyl ring and carbazole ring are about 70°, resembling that of the previously reported clusters.…”

“…[14,15] The presence of both intraand intermolecular gold(I)•••gold(I) interactions has allowed the formation of polynuclear gold(I) chalcogenido clusters with diverse structural, photophysical and photochemical properties. [16][17][18][19] Monodentate phosphine ligands were first used to construct polynuclear gold(I) chalcogenido complexes back then, [20][21][22][23][24][25][26] because they could greatly improve the solubility and stability of polynuclear gold(I) chalcogenido complexes. [20][21][22][23][24][25][26] Interestingly, the employment of phosphines with different denticities can afford clusters with unprecedented shapes, structures and interesting chemical properties.…”

Decanuclear gold(I) sulfido clusters, [Au10{μ‐Ph2PN(C6H4−Cbz)PPh2}4(μ3‐S)4](PF6)2 (1) and [Au10{μ‐Ph2PN(C6H4−tBu2Cbz)PPh2}4(μ3‐S)4](PF6)2 (2), with bridging bis(diphenylphosphino)amine ligands were synthesized and characterized. The propeller‐like molecular structure of 1 was determined via X‐ray crystal structure analysis. Both complexes were found to show intense dual green and orange phosphorescence upon photoexcitation at ambient temperature. The emissions were tentatively assigned to originate from the excited states derived from the phosphine‐centered intraligand (IL) transition and ligand‐to‐metal‐metal charge transfer (LMMCT) (S→Au) transition.

“…The crystal structure of compound [Au 5 (m-S) 2 (PPh 3 ) 4 ][SnMe3 Cl] has been reported and confirms the triply bridging nature of the sulfur ligand. In the cation one gold atom bridges two Au 2 (m-S)(PPh 3 ) 2 units but there is no gold-gold interaction between the bridging gold atom and any other in the molecule(Figure 2.26)[133].The use of chalcogen atoms and diphosphines as building blocks in the same molecule allows the synthesis of derivatives with higher nuclearities. The crystal structures of the hexanuclear species [Au 6 (m-Se) 2 (dppf) 3 ] 2þ(Figure 2.27a) and [Au 6 (m-S) 2 {Ph 2 PN(p-CH 3 C 6 H 4 )PPh 2 } 3 ] 2þ have been reported.…”

This chapter focuses mainly on closed shell gold(I) atoms which are found to feel attraction among themselves. This attraction is able to modify expected geometries or support one-, two-or three-dimensional arrays and also leads to interesting properties. Closed shell metal cations are expected to repel each other. Nevertheless, an important number of examples containing [d 8 -d 10 -s 2 ] interactions are known. Particularly strong evidence has been accumulated on the attraction between two or more d 10 shells. In the case of gold(I) such attraction between two or more monovalent gold(I) ions in compounds has been observed structurally for a long time. In these situations the gold centers approach each other to a distance of between 2.7 and 3.3 Å. This range includes the distance between gold atoms in gold metal and approaches, or even overlaps with the range of distances found in the few real Au-Au single bonds. Schmidbaur coined the name aurophilic attraction in 1990 and defined it as the unprecedented affinity between gold atoms even with closed-shell electronic configurations and equivalent electrical charges [1]. Since that moment, aurophilicity has become one of the hot topics in gold chemistry, at first with the aim of understanding such interaction, more recently because of the observation that it may play an important role in interesting properties, thus understanding and modulating aurophilic interactions could help to govern these properties, which include the optical behavior. Although different origins are possible for the luminescent emissions of coordination complexes, such as intraligand transitions (ILT), ligand to metal or metal to ligand charge transfer transitions (LMCT, MLCT) and metal centered (MCT) transitions, in many luminescent gold complexes the emissions have been related to the presence of aurophilic interactions.Information about aurophilicity and chemical situations in which it is observed may be found in different works that may be classified as those which analyse closed shell interactions in general [2], those focused on aurophilicity [1,3], and others which analyze the role of these interactions in coordination [4] and organometallic gold Modern Supramolecular Gold Chemistry: Gold-Metal Interactions and Applications.
